PRINTING AND BINDING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 452,933, dated May 26,1891.

Application filed September 30, 1886. Serial No. 214,926. (No model.)Patented in England September 20, 1886, No. 11,953; in France April 11,1887, No. 170,600, and in Belgium April 15, 1887, Nx 76,893.

To ctZZ whom it may concern.-

Be it known that I, HENRY P. FEISTER, of the city and county ofPhiladelphia, and State of Pennsylvania, have invented an Improvement inPrinting and Binding Machines, of

which the following is a specification.

My invention has reference to machines for printing and bindingpamphlets or books direct from a roll of paper; and it consists in IOcertain improvements, all of which are fully set forth in'the followingspecification, and shown in the accompanying drawings, which form partthereof.

This invention was patented to me in Great [5 Britain on September 20,1886, No. 11,953; in Belgium on April 15, 1887, No. 76,893, and inFrance on April 11, 1887, No. 170,600.

The object of my invention is to make in an automatic manner a largenumber of books from a roll of paper, and to accomplish this object thepaper is required to go under the following operations: As the paper webpasses into the machine the book-sheets are cut off prior to printing,and are then printed, first on one side and then upon the other, in themanner hereinafter set forth, and after being printed upon both sidesthe said book-sheets are assembled sheet after sheet on top of eachother and in perfect register and folio. These 0 sheets in the act ofbeing assembled are pasted together down their central margin, and thebook so formed is secured to its cover, and the entire assembled sheetsand cover are folded through their center margin and then subsequentlytrimmed where a particularly nice finish is required.

In carrying out my invention I provide two segmentalimpression-cylinders and one segmental type-form cylinder, the twoformer working in contact with and cog-geared to the latter and rotatingin the same direction at point of contact, so that one prints fromalternate type-forms and the other prints from the type-forms omitted bythe first With these I provide suitable feed guide and cut tingcylinders,which perforate the sheet transversely across and feed it toone of the impression-cylinders ata rate of speed equal to one-half thatof the impression-surfaces upon 5o said cylinder; but its feed is sotimed that the edge of the sheet will come in line with the forwardadvancing edge of the impressionsnrfaces, where it is gripped bysuitable automatic nippers fitted to and working with the forward edgeand carried around between the said impressionsurfaces and the typeform-cylinder segments. If the sheet were wholly cut from thecontinuously-traveling web, there would be difficulty in its properdelivery to the nippers, as said nippers could not catch the paper tillthey had passed and descended beyond the cuttingcylinders a distanceequal to the length of the sheet, owing to the different velocities oftravel of said cylinder and sheet. It would be impracticable to relyupon the nippers holding the sheet. so

as to break or detach it from the web. To accomplish this result, Iprovide a sheet-detacher consisting of a series of pins arranged atright angles to a revolving shaft and 7c adapted during their revolutionto work in contact with the advancing or leading edge of theimpression-surfaces of the impressioncylinder, and thereby at statedintervals nip the sheet and break it from the web, and '7 5 at the sameinstant therewith the nippers close upon the leading edge of the sheet,and it is carried forward in perfect registera with marginal allowanceto meet the forms on the segmental form-cylinder. After the sheet iscarried between the type-form or printing cylinder and the firstimpressioncylinder it is carried around and transferred by a suitabletransfer device, such as set out in Letters Patent No. 323,925, anddated August 11, 1885, to the second impression-cylinder, which isrevolving in the same direction as that of the first impressioncylinder,and the nippers upon said second impression-cylinder close upon the tailend of the sheet, while the nippers upon the first-mentioned cylinderopen to free the forward end of the sheet. It will now be seen that whatwas before the leading edge of sheet now becomes the tail2l e., reversedin its motion, so that the printed face of the sheet is now turned downupon the second impression-cylinderand as it is carried between theimpressionsurface and the type-form cylinder the 0pposite or reverseside will be printed. The

sheet now being printed upon both sides, it is carried around the lowerhemisphere of said second impression-cylinder and up and delivered to anassembling device located at the rear of the machine. The transferdevice consists, essentially, of a hinged frame or tympan, the rear endof which swings out at the proper time through the agency of camdevices, so as to throw the tail end of the sheetwvithin reach of thenippers upon the second impression-cylinder. The type-form cylinder hasa continuous series of type-forms about its circumference, which may beeither curved or fiat and receive ink from station ary inking-rolls ofany of the well-known constructions. When curved type-forms are used,then the type-form beds orsegments to which they are secured arearranged rigidly upon the cylinder, their curvature being the same asthe pitch curve of the said cylinder; but when flat plates are used,then these beds are pivoted in such a manner that they may rockslightly, so that each portion of the typesurface may at the instant ofprinting be brought in line with the pitch circle, and thereby have allthe effect of a curved plate. This is accomplished by. providing thesaid type-beds with bearer-plates 011 their ends, which shall run incontact with like curved surfaces on the impression-cylinders, the faceof said bearer-plates being as tangents to the pitch circle. Thetype-form beds or segments are adj ustably pivoted in this latterinstance and held in position by suitable springs, which may be eitherof metal or rubber and are provided with devices whereby their out- 1ward or radial adjustment may be regulated so as to insure the requisitedegree of printing-pressure. As constructed these type-form 7 beds maybe made rigid or adjustable to suit curved or flat type-forms. Thetype-form beds or segments are made rectangular in shape and areprovided upon each end with journal lugs or studs, by which they areheld through the agency of suitable links to a pair of Wheels orspiders, which wheels are adjustably secured upon and between thegear-wheel and blank wheel forming th two outer walls of the type-formcylinder. The type-form gear meshes with the corresponding gears uponthe impression-cylinders, and while it is found in practice that asingle set of these gear-Wheels and a set of blank wheels aresufficient, yet it is evident that the blank Wheel may also be agearwheel. Both of these wheels are secured firmly upon a shaft, and thepair of spiders or type-form-carrying Wheels are supported upon the sameshaft and adjustably clamped by means of bolts or slots to the said gearand blank wheels, preferably near the periphery, whereby said spiderswith their type-forms may be adjusted back and forth in the pitchcircle. From this it will be seen that the internal wheels or spidersand the segmental type-form beds are adjustable either with or againstthe direction of the travel of the typei'orm-cylinder gear andindependently of the position of the teeth in same. This adjustment isvery important, as it is by this means that books of different sizes areenabled to be printed on the same machine. These type-form beds areprovided with a slot extending almost from end to end, through which theform-clamps pass and are made adjustable laterally upon the bed. Theseclampsare provided with pins orpoints upon their. sides adapted to catchor hold the typeforms down upon the beds. These clamps project throughto the under side ofthe bed,

and are provided with enlarged portions through which the clamping-boltpasses. One end of this clamping-bolt is made in two parts, one part ofwhich is screwed into one end of the bed, and is connected to the otherpart by a right and left hand screw-threaded coupling, so constructedthat upon being turned the clamping-bolts will be drawn together. Thefree end of the last-mentioned bolt is provided with a head which drawsupon the end clamp, and this through the mediation of the type-formpresses upon the next clamp, and so on, clamping all of the type-formsfirmly in position upon the bed. As many or few of these adjustableclamps may be used as are desired, as they are capable of being placedupon and removed from the bed at will. The construction of the type-formcylinder is novel in every particular, admitting of lateral adjustmentof the clamps to hold type-forms of different widths or also ofdifferent lengths to suit books of different sizes. The maximum speedmay be obtained as each cylinder revolves constantly in the samedirection at point of gear-mesh.

The advantage of the above-mentioned adjustable features will be readilyappreciated when it is understood that the only limit to the size of thebook or books capable of being printed upon this machine is the maximumwidth and length orlinear dimensions of the type-form beds or impression-surfaces, as each impression-surface may print laterally oneor more book-sheets at one time, as desired, and as governed by theprevious adjustment. The sheets, after being printed upon both sides,may be delivered upon a fly-frame and used as circulars or bound in anymanner desired; but I prefer to assemble them upon an assembling device,and then after the required number of sheets have been assembled deliverthem to a folding mechanism. The assembling device consists of askeleton frame revolving in unison with another or pastingfountain-frame, the former of which is provided With a series ofadjustable springband sections to support the assembled sheets, and,further, with two sets of nippers, one of which sets is for the purposeof holding the leading edge of. each sheet as they assemble on eachother, while the other of which sets is for the purpose of taking andholding the leading edge of the sheet from the impression-segments ofthe second impression-cyl- IIO inder as delivered until thefirst-mentioned set of nippers is withdrawn from under and placed on topof the sheet. The assembled sheets are successively clamped upon aradially-movable bar supported upon springs, which, with the forwardedge of the sheets collected, is depressed by a cam on each sideconnected with a pin-bar (the purpose of the pin-bar is to distributethe buckles and wrinkles in each sheet as they assemble on saidskeleton) as well as to hold the leading edge of the sheet close to theradial bar on the assembling-frame, so as to insure the retainingnippersgetting on top of said sheet as the bar rises, thereby allowing at onepoint in the revolution of the assemblingskeleton a proper working ofthe holding-nippers. These nippers are worked by suitable cam devices,so as to operate with each revolution of the skeleton frame to assembleand hold the lead ing edge of one or more sheets, and they are soarranged that after a given number of sheets are assembled asuitable camoperates to throw them entirely out of action, whereby the sheets arereceived upon the fly-frame, which has been tipped sufficiently to passunder the said sheet-s as their leading edges advance toward it. As theleading edge of each sheet is taken off the impression-segments of thesecond impression-cylinder the sheets naturally lie on top of theretaining or holding nippers, and said retainingmippers by suitable cammechanism are actuated to withdraw from under the sheet just prior tothe depression of the radially-moving bar and to again close in thecurvature of the pitch circle of the gears (by which theassembling-skeleton is driven) while the said moving bar is depressed.As the moving bar again rises it clamps the sheet or sheets against theretaining-nippers. The object of this radially-moving bar is to allowthe withdrawing of the retaining-nippers from under the sheets and theirpassage above the same, and this is attained by causing the sheet tomove down with the said bar after the retaining-nippers have been drawnback, so that upon the advance of said nippers the retaining part comesover the leading edge of the sheet, and when the said bar again rises itclamps the sheet against the said retaining-nippers. The leading endsof, say, four of the spring-bands of the assembling device are leftloose in a measure compared with the others, so that they will press theleading edge of the sheets against the like edge of theimpression-cylinder segments in order to prevent the sheets slippingduring action of delivery of sheet to the assembling device, as for aninstant of time the sheet at this period is not in the custody of anynippers. The upper of said assembling devices is provided with anair-tight pastefountain arranged to automatically feed the paste witheach revolution to place upon the last sheet as assembled as aforesaid atrans verse line of paste, whereby the successive sheets are pastedtogether. Said paste-fountain is adjustable with the radii of pitchcircle of the gears by which the paste-fountain and assembling-skeletonrevolve in unison, this being necessary in order to paste books ofdifferent sizes, they always being pasted down the center or foldingmargin. After the assembled and pasted sheets are delivered to thefly-frame they are laid upon the table upon which the back or cover hasbeen previously placed or inserted, and the upper or exposed line ofpaste attaches the covers to the assembled and pasted sheets. Thepastefountain carried by one of the skeleton frames above mentioned maybe counterbalanced to make it run smoothly, and the paste may be fed tothe fountain while the machine is running. The paste-fountain consistsof an air-tight receptacle having an orifice open ing upon the pitchcircle and furnished with two preferably adjustable plates, betweenwhich the paste-roller is intermittently rotated by suitable cam oreccentric devices, one of which plates lets out the paste and the otherscrapes it off, whereby a limited amount of paste is brought to the faceand applied to the book-center margin or foldingline with the receptionof each new sheet, avoiding all excess which would tend to cause troublein the proper binding of the books. This paste-fountain, as aforesaid,is adjustable on the pitch circle and about the center of the semicircleof the skeleton frame to which it is attached, whereby it may be causedto apply paste on the folding-line of books of different sizes. This isnecessary where it is desired to print books of different sizes on thesame machine. After the pasted sheets have been delivered by thefly-frame a folding-knife descends, folding the sheets and cover into abook form, and which folded sheets may be run between trimming-knives orbe subsequently out. If the machine is made of sufficient width, two ormore pamphlets or books may be made and formed end to end and may besubsequently cut apart. The bound signature, after passing through thefolder, is received by a packer, which presses each successive bookbackward in the rear of suitable spring-pawls, which retain it in thedesired position and clear of the book next entering. The secondimpression-cylinders, receiving the printed sheets printed side down,are apt to have their tympans more or less inked by the reception ofsuccessive printed sheets and the consequent pressure to which they aresubjected. To prevent blurring of sheets from this cause, I provide amovable tympan or make-ready Web and a suitable device for moving itautomatically with each impression, whereby each successive sheet isreceived upon a different portion thereof. The roll of paper issupported upon a carriage or frame, which is pivoted to'a bed upon avertical center, the obj ect being to allow the paper to feed uniformlyto the feed and perforating cylinders, and

thereby overcoming defects due to the (litterence that is sometimesfound between the lengths in a given distance of the two lateral edgesof a roll of paper.

D is the main frame-work of the machine and supports the twoi-mpression-cylinders A and B, both rotating in the same direction, butnot in contact with each other, and the type-form cylinder O, with whichboth of the impression-cylinders work, the organism being such that theimp ression-cylinderA prints from certain type-forms of the cylinder 0,and those omitted by the said impression-cylinder A are printed from bythe cylinder B, substantially in the manner set out in Letters PatentNo. 256,662, and granted to me April 18, 1882; also Letters Patent No.323,925, dated August 1]., 1885; but in this application I havesubstituted a chain or series of typebeds in the form of a cylinder. Theimpression-cylinder A is provided with a series of iimpression-surfacesa, separated by an equal distance, and the leading end of each of saidiimpression-surfaces is provided with suitable paper-clamping nippers G.

The roll of paper E is loosely supported upon a frame E, which isallowed to oscillate in a horizontal plane by means of a vertical pivotE formed in the base-plate Eiwhich in practice rests upon the floor. Bythis means inequalities in the lengths of the edges of the paper webwill not cause a dragging effect upon the feed and cutting rolls F. Thefeed and cutting rolls consist of a roller F, having perforating pointsor cutters f, and the roller F having notches or grooves into which saidperforating points or cutters project. These rollers are geared togetherby spur-gears F, (see Sheet 1,) whereby they are caused to run in unisonand perforate the web of paper to form two sheets with each revolution.These rollers do not entirely sever the sheet, but simply put it in sucha condition that it is easily broken or detached from the web. Thesurface speeds of these perforating cylinders or rollers are one-halfthat of the impressioncylinder A, so that the leading edge of eachsuccessive sheet delivered to the impressioncylinder shall coincide withthe leading edge of each of the impression-surfaces a. Theseperforating-rolls are driven by gears F F, the former of which issecured to the impressioncylinder A or its shaft A F is the rotatingshaft, to which are secured a series of detachingpins f, and said shaftis rotated by a gear A which meshes with the teeth A of theimpression-cylinder A. (See Fig. 2.) The object of this detacher is tocatch at stated intervals the forward edge of the sheet by pressing itagainst theimpressioncylinder, and for an instant of time cause it totravel at double the velocity that it would otherwise have. The effectof this is to break the sheet away from the web along the lines ofperforations, and the instant this is done the nippers G fly down andclamp the leading edge of the sheet to the impression-surface a.

These nippers are secured to a cross rockshaft G, journaled on theimpressioircylinder between the impression-surfaccs, and has secured toits outer end the pinion g, which is rotated by a segmental lever Ghaving rollerg', which runs against the nipping and releasing cams forthe purpose of oscillating the segment to open or close the nippers Thenippers are normally kept closed by means of a rod G and spring 9e,connecting with the segment G the said springs opposing the action ofthe cams.

H is the nipping-cam, which is secured to an arm 11, journaled on theshaftof the impression-cylinder, and said cam is adjustable in the arcof a circle by means of a slot h and bolts h, passing through the mainframe of the machine. This cam H is so located that it opens the nippersfully to pass under the sheet perforating rolls and allow them to closequickly immediately upon the sheetbeing detached,as hereinbeforedescribed. The sheet so delivered to the impression-cylinder A iscarried past the type-form cylinder and receives an impression upon oneside, and is then carried on until it comes directly opposite to theother impression-cylinderB, when it is transferred by a suitabletransfer device, set out in Letters Patent No. 323,925, above referredto. This transfer device consists, essentially, of a tympan I, securedat its leading edge '2' to the leading edge of the impression-surface aof the impression-cylinder A. This tympan is connected by a link i nearits middle and is swung out at the proper instant by said link, which ishinged to a lever I, secured to a rock-shaft 1 which rock-shaft isrocked by means of a lever I and reciproeating bar I, having a roller iworking in a stationary cam I. This cam has but one operating part, andthat is solocated as to make the various tympans or transfer-framesoperate at one particular place in the revolution of theimpression-cylinder. Each of the impression-surfaces a is provided witha similar tympan and mechanism to operate it, though for simplicity andclearness only one such complete device is shown in Fig. 3. The instantthe tympan moves the tail end of the sheet over to the cylinder Bthe-nippers G are caused to release the leading edge of the sheet ofpaper by means of a releasingcam Il secured to a radial arm Hijournaledupon the axle A, and made adjustable in the are of a circle by means ofthe slotted liukand-bolt device ll", connecting with the main frame ofthe machine. In addition to this adjustment, the cam 11 is adjustable bymeans of a slot or bolt connection 7L2 to and from the center oftheinipression-cylinder to control the degree of opening of the nippers.The instant the sheet is thrown to the cylinder B and is released by thenippers on the cyl inder A it is caught by the nippers G on the cylinder13, the tail end now becomes the leadingend of the sheet, and theprinted surface lies adjacent or next to the impressionsurface. Thesheet is now carried between the type-form cylinder 0 andimpression-cylinder I3, and its reverse side is printed upon by one ofthe type'forms omitted by the cylinder A, and after being thus printedupon both sides the sheetis carried around and delivered to theassembling device M. The impression-cylinder l is in all materialrespects the same in construction as the cylinder A, with the exceptionthat it has no transfertympans. It is combined with similar cams H tooperate the nippers to close upon the forward or leading edge of thesheet and the releasing-cam H to release the sheet when in the act ofbeing delivered to the assembling device.

To prevent blurring of the sheet when in the custody of the secondimpression-cyliir ders B, I provide the impression surface thereof withmovable make-ready webs b, which may be intermittently wound from oneroller B to another, traveling to a slight extent with each impression,so that every time a fresh sheet is received upon the impressionsurfaceI) the inked portion thereof is received upon a different portion of themakeready. This make-ready web may be moved automatically in a largenumber of ways, that shown in Fig. 8 consisting of a ratchet-wheel Z2attached to one of the rollers 13', combined with a stop pawl I)" and apivot-pawl and lever-actuating device B which is reciproeated with eachrevolution of the cylinder B by being brought into contact with thestationary cam B.

The type-form cylinder 0 consists of the two main wheels, one or both ofwhich may be provided with gearing C to engage with the teeth on theimpressiou-cylinders, and thereby be caused to revolve in unisontherewith, and to the inner faces of the said main wheels are adjustably secured spiders or formsupporting wheels 0, which are adjustableupon the shaft 0 to which the main Wheels are secured. The form-wheels Oare adjustably bolted, by means of the bolts 0 and slots 0, to the mainwheels near their periphery for the purpose of accurately adjusting therelative position of the type-forms with re spect to theimpression-surfaces without disengaging the main wheel or wheels of theform-cylinder from the gears of the impression-cylinders, and,furthermore, this adjustment admits of a very small variation inpositionof the type-beds, whereasif adjustment were made by shifting thegears relatively to each other it would necessitate at least a movementequal to the distance between the centers of two adjacent teeth. Thisadjust ment is extremely important, as it is the means whereby books ofdifferent sizes may be printed upon the same machine, and enables theadjustment to bennade with respect to the leading edge of the sheet, andthereby insure the impression to be properly located.

C are the type-form beds and are connected to the wheels 0 by means oflinks or eyebol ts IIO K, connecting at one end with lugs c" on the endsof the type-form beds and at ihe other end connected by nuts K anda'spring K with a flange of the wheels 0. The spring K may be made ofmetal or simply a rubber washer. These links or bolts perform a function of holding the form-beds 0 in the proper radially adjustment, soas to keep the print-- ing-surface of the type-form in a line with thepitch circle of the impression and typeform cylinders, and therebyinsure accurate and good printing. To prevent the form-beds from beingforced toward the center of the form-cylinder, I provide bolts K havingsemicylindrical heads K, which fit into corresponding recesses 0 uponthe ends of the form-bed and upon each side of the lugs 0 each boltreceivinga pressure from two adjacent formbeds. These bolts are guidedthrough bearings K and are supported upon springs K the tension of whichmaybe adjusted by nuts K". From this construction (see Sheets 3 and 4)it is evident that the form-beds will be free to rock so as to bringevery portion of the printing-surface of a flat form at the instant ofprintinginto the pitch-line or curved plane through the face of theimpression-surface. To remove the pressure necessary to rock these bedsfrom the type-forms, I provide upon each end of the bed a hardened steelbearing-plate, which rocks against the surface of theimpression-cylinders and causes these beds to rock in a manner to printwithout undue pressure upon the type-form. If curved type-forms, such asindicated in Fig. 6, be used, then it is not necessary to rock the bedC, and in that case curved bearer-plates would be substituted for thefiat or tangent plates, as indicated in dotted lines in Fig. '7. In thiscase the springs K around the bolts K might be removed and metallictube-sections K substituted therefor, (see right-hand portion of Fig.5,) which change would make the parts K rigid, and by proper adjustmentof the nuts K the adjustment of the beds could be made to a nicety. Itis evident that these details of construction might be modified invarious ways and yet attain the same results. I therefore do not limitmyself to the specific devices shown. As the bolts K and K are carriedby the inner wheel 0, it will be perceived that these beds are alsonecessarily carried by said wheels and are adjustable with them. Thismethod of construction enables the machine to be changed to make thebeds rigid or adjustable to suit curved or fiat type-forms, as the casemay be. These beds are provided with a longitudinal slot through whichthe form-clamps 75' are adjustably connected to a tension-bolt 10located in the under part of the bed, upon which they are threaded.These close to the bed. These clamps have a head on their lower parts,through a hole 70 of which the tension-bolt 7c passes. These clamps areinserted from one end of the bed before the bearer is secured in place,and the end clamp, or the one last placed on,isdraWn up against the endtype-form J and by arranging the clamps and the type-form, alternately,as indicated in Figs. 4 and 8, they may be clamped firmly in position,the clamping action being transmitted from one to the other, and the endform being pressed against the retaining-teethon the bearer 7c. Tocreate the tension I make a bolt 70 in two parts, each of which has ahead 7c ,one of which heads pulls against the end of the form-bed andthe other of which head pulls againstthe last clamp 70, and these twoparts of the bolt are drawn together by a right and left handcouplingpiece 70 as shown in Fig. 8. From this it is seen that byturning the coupling all of the type-forms may be clamped securely tothe form-bed, and by varying the number of clamps any desired number orsizes of typeforms may be used.

In a machine of this class where there are a number of forms arrangedend to end transv versely across the cylinder it is evident that eachtype-form on each bed may be used to print a corresponding page in asmany books as there are type-forms on each bed; or, if desired, thesheets printed from two or more such type-forms may be used assignatures and ultimately bound together into the same book. Thus,forinstance, a machine holding five type-forms upon each bed and havingsixteen beds would be capable of printing five books of sixteen pageswith each revolution, or one book of eighty pages; or if we have twobeds to each impression-surface these figures will be doubled, and itwill thus be seen that the capacity of the machine will be enormous.

L is the inking-rollers for the form-cylinder, and are driven by a beltZ, passing around a pulley L, secured to the shaft C of theformcylinder.

J is the main drive-wheel or band-pulley, from which power istransferred to the machine by. pinions J, meshing with the teeth B ofthe impression-cylinderB. The arrows on the different figures indicatethe direction of travel of the various parts.

The sheets printed in the manner above described may be delivered by asuitable fiyframe or delivery apparatus and be used as circulars in theloose form, or they may be collected and bound in book form, by asuitable apparatus now to be described.

The binding apparatus consists of two parts-the assembling device bywhich the sheets are assembled upon each other one after the other andare pasted together down the center of their middle margins, and thefolding device for folding the sheets so collected and pasted. Thesedevices are clearly shown in Fig. 1 and Figs. 15 to 28, inclusive.

a series of arms M The assembling device M consists, essentially, of twoskeleton frames revolving in contact with each other, one of said framesM being the asscmbling-cylinder, while the other M carries thepaste-fountain and applies the paste to the sheets as they aresuccessively assembled on the assembling-frame. The assembling-frame issupported upon an axle 18 or shaft M", to which is adjustably clamped Tothese arms are secured a corresponding series of flexible springbands Mwhich are curved around, forming asemicircle and giving the appearanceto the frame of a semi-cylinder. Diametrically oppo- U sitetothearmsMisaradiallymovingchangerbar M adapted to move to or from the shaft M,and is pressed away from the said shaft by rods M, near each end, andsprings M The ends of some of the bands M" are secured to brackets m inturn bolted to the radiallymoving bar M so as to be depressed with thesaid bar, while others of said bands have their ends m free, asindicated in Figs. 17 and 18, the purpose of which will be hereinafterset out. The skeleton frame so formed revolves upon its axis M and movesin unison, by means of gearing 0"", with the frame M carrying thepaste-fountain and revolving upon an axis 0. The frame M is providedwith the cams P, arranged to be adjusted about the axis 0 by means ofslots 19 and screws 1). These cams are set so as to strike theradially-moving bar N once in every revolution and cause it to bedepressed when the retainingnippers are in the act of being shifted.(1onnecting these cams P is a crosspin bar P carrying a series of pinsP, longitudinally adjustable in the direction of their length andarranged radially with respect to the axis 0. The object of these pinsis to cause the leading edge of the paper sheets to be held down uponthe radially-moving bar in such a manner that any buckles formed thereonshall be pressed down or distributed, thereby reducing all wrinkles andbuckles to a small size and insuring the retaining-nippers being freelypassed above the leading edg of the sheet. The frame M is provided withtwo sets of nippers, one set on, called the retaining-nip pers, and theother set 072 or receiving-nippers. These two sets of nippers arerespectively secured upon rock-shafts m and m and are equal in number,being arranged side by side, as shown in Figs. 16 and 17, the pins P ofthe pin-bar working between them. The nippers m are designed to catchevery sheet from the impression-cylinder B just as the nippers G of theimpression-cylinder are released by the delivery-cam H whereas thenippers m are simply designed to hold the assembled sheets collected bythe action of nippers m while the said nippers m are raised in the actof catching the leading end of a fresh sheet. The action of thesenippers at this part of their movement is clearly shown in Fig. 18.After a fresh sheet is assembled upon those already resting upon thespringbands M the said nippers an hold it till the next sheet is to bereceived, merely opening and closing once in a revolution, (except whendelivering the assembled sheets to the folden) and then when it is closeto the impression cylinder R. hen the leading edges of the assembledsheets approach a vertical line through the axis of the cylinder M, theretaining-nippers m are drawn from under the last-assembled sheet, andas the movement continues the cam P on the frame M depresses theradially-moving bar with its assembled sheets, as indicated in Fig. 19.At this in stant the retaining-nippers m are allowed to move back overthe top of the leading edges of the assembled sheets, as indicated inFig. 20, and as the cam P is lifted from the radially-moving bar thesprings M cause'the said bar to move away from the axis M and clamp thesheets between itself and the retaining-nippers. The retaiuing-nippershaft is caused to rock by means of a spring m", so as to normally closethe nippers into operating position, and when said nippers are to beturned from under the last-collected sheet this operation is performedthrough the agency of crank m having the roller m which works in contactwith the stationary cam M (See Figs. 17, 21, and 22.) After the proper number of sheets have been assembled and it is desired to discharge themto the fly-frame Q, by which they are delivered to the folding portionof the machine, the retaining-nippers m are thrown back a greaterdistance by means of a delivery-cam M ,connected to a lever M pivoted atm to the main frame of the machine and combined with a spring m" tothrow the cam M" out of action. The free end of the lever M is 0011-nected to a link N, guided on the main frame by a slot n and lug 71 andthis link is provided on its end with a roller 01, with which one ormore cams B 011 the impression-cylinder B (see Sheet 7) work. \Vhen thecam B shifts the link N, it raises the delivery-cam M into thepositionindicated in dottedlines, Fig. 21, so that as the roller 9723for operating the nippers travels around its overhang runs upon thedelivery-cam and causes the nippers to open to allow the delivery of theassembled sheets. The nippers m are operated by a pinion and segmentalgear similar to those upon the impression-cylinders for operating thenippers thereof.

Referring to Sheet 5, it will .be seen. that the nipper-shat't m isprovided on its end with a pinion N, with which the segmental gear Nmeshes. This segmental gear is operated to open the nippers by means ofa spring N and to close the nippers by means of a roller 12. carried bythe segmental gear and adapted to follow the face of the station ary camN". This segmental gear and its spring N are secured to the frame M, andare thereby caused to travel about the stationary IIO cam. It will beobserved that the nippers m are thrown out of action by a cam, whereasthe nippers m" are thrown into action by a cam.

Q is the fly-frame, which may be of any ordinary construction. Referringto Fig. 1, it will be observed that this fly-frame has imparted to it anoscillating movement about its axis by means of a pinion Q, operated bya segmental gear upon a bell-crank lever Q This bell-crank is formedwith adjustable arms connected by an adj usting-link q for the purposeof regulating the position of the fly-frame. This bell-crank has aroller g, which works upon the cam Q which has the extended part and thedepressed part Q", the said bell-crank being pressed toward said cam bymeans of a suitable spring (1 This cam Q is secured to the shaft 3 ofthe impression-cylinder B, and makes one revolution to each revolutionof the impressioncylinder. The object of the depressed portionQ, of thecam is to allow the fly-frame to drop into the position indicated indotted lines, Fig. 15, so that as the assembling-frame M revolves aroundthepoints of the fly-frame pass through the notches m in theradiallymoving bar, and hence the leading edge of the assembled sheetsis brought above the fly-frame and may be delivered thereto, as at thisinstant the nippers will have released their hold upon the assembledsheets, and said sheets in running down upon the flyframe will passunder the rubber rollers 0 upon a shaft 0 Upon the end of this shaft isa pinion O, which meshes with the gears O of the frame M. The camportion-Q of the cam Q then operates the bell-crank lever to cause thefly-frame to deliver the sheets upon the receiving or folding table R.

We will now return to the pasting devices for securing the sheetstogether by means of a line of paste down their middle margin.

Referring to Sheets 5 and 6, N is the airtight paste-fountain adjustably secured to the frame M (which revolvesin unison with frame M,)and is made circumferentially adjustable by means of slots 0 and screws0, whereby it may be adjusted with reference to the leading edge of thesheet, and thereby insure the deposit of paste in the proper position inthe middle margin with book-sheets of different sizes. Thepaste-fountain is located upon one side of the hollow shaft 0, and iscounterbalanced by a weight N to prevent the excessive action ofcentrifugal force. The paste-fountain may be charged while the machineis running by forcingthe paste through the hollow axle O and the branchpipe 0, which connects the hollow axle with the paste-fountain, and whenthe fountain is full such condition will be indicated by the oozing ofpaste from underthe detecting and air-vent springvalve 0.

N is the paste-feeding roller, and revolves with an intermittentmovement back of a narrow slit of, extending the full length of thepaste-fountain and formed by the edges of the adj ustablcscraping-plates N which regulate the amount of paste admitted to theslit. The paste-roller N is operated by the eccentrio and ratchetmechanism shown in Sheets 5 and 7, from which it will be seen that thesaid roller is provided on its end with a ratchet-wheel a which isintermittently r0- tated by a pawl or, operated by a lever n pivoted tothe axis of the ratchet-wheel and reciprocated by means of theeccentric-strap O' and stationary eccentric 0 arranged about the axis 0of the frame M From this it will be seen that as the paste-fountain iscarried about the stationary eccentric the ratchetwheel will beintermittently rotated and cause a corresponding motion to the pastefeed and roller N". There would be enough playin the adj ust-ing-slot Oto allow a slight adjustment radially to or from the axis 0 of thepastefountain. The sheets on the frame M when receiving paste aresupported by the springbands M, and said spring-bands may be adjusted bymoving arms M so as to spring their curvature, as indicated in dottedlines, Fig.15, and thereby increase or diminish their adjustment towardthe paste-fountain. The frame M is formed with the spring-bands Mseparated from each other by space, so that when the sheets are beingdelivered to the fly-frame the arms of said fly-frame may enter betweenthe said spring-bands, so as to bc under the sheets supported thereon.

From the above construction it will be observed that as each successivesheet is assembled upon the assemblingframe M the Pastefountain depositsat line of paste centrally hrough the middle margins of the sheets socollected, whereby the said sheets are secured to each other, and uponthe said sheets being transferred to the folding-table they are causedto be laid upon a cover which has been placed face downward, and thelast deposit of paste upon the printed sheets will come next to thecover and secure it to the book.

R is the receiving-table of the folding device and is provided with atransverse slot 9', beneath which are the pressure-rollers R, aroundwhich endless bands 0' travel.

S is the folding-knife secured to a rocking lover s, and is adapted tofold the assembled and pasted sheets and back on their middle margins,and such folded sheets and back are fed between the rollers R and theirhands and are deposited upon the packing-table U. They are then forcedback by a reciprocating slide XV to the rear of two spring-pawls t, andbetween said pawls and a retaining-frame U, which is constantly drawntoward the said pawls by a chain u and weight a. As the books accumulateat V the frame U moves back, but at the same time holds them in a packedcondition. The folding-knife S and its arm are operated by a levers andlinks 8, which are acted upon by a cam T, secured to the axle of theimpression-cylinder B. The slide W is also operated from the same lovers bya link w, and said lever s is caused to follow the face of the camby means of a spring device X is a spur-wheel connecting theassembling-cylinder gears O and O with the folding-rollers R, wherebythey receive motion. The assembling-cylinders receive their motion fromthe impression-cylinder B, and have the same surface speed therewith.

I would remark that I do not limit myself to the details of constructioninvolved in this machine, as such details maybe greatly modified withoutin any wise changing the principle of the invention, and it will bereadily understood that almost any form of a folding and packing devicemight be used with a machine of this class.

The practical operation of this machine has developed the fact that thespeed may be very great without the least injury to the cleanness of theimpression or the register of the sheets. The work printed upon thismachine, in view of the improvements herein set out, is equal to that ofthe best printing-presses with flat reciprocating beds, and theassembling and binding are so perfect that trimming is not absolutelynecessary.
